Proteins that are not of animal origin but are derived from other protein sources. Alternative protein sources already in use today are predominantly of plant origin. They include, for example, wheat, soy, peas, beans, lentils, cashews, jackfruit or lupins. Higher fungi and insects also already serve as protein sources. Recombinant microorganisms, which produce animal-identical proteins in fermentation processes, represent another pillar. Proteins from cell cultured meat cultivated in the laboratory could also contribute to an animal-free diet in the future.
